Dental Insurance Plus – Wipe Out Dental Plaque
An army of micro-robots can wipe out dental plaque
A swarm of micro-robots, directed by magnets, can break apart and remove dental biofilm, or plaque, from a tooth. The innovation arose from a cross-disciplinary partnership among dentists, biologists, and engineers.
A team of engineers, dentists, and biologists from the University of Pennsylvania developed a microscopic robotic cleaning crew. With two types of robotic systems — one designed to work on surfaces and the other to operate inside confined spaces — the scientists showed that robots with catalytic activity could ably destroy biofilms.
Such robotic biofilm-removal systems could be valuable in a wide range of potential applications, from keeping water pipes and catheters clean to reducing the risk of tooth decay, endodontic infections, and implant contamination. Source: University of Pennsylvania
